The question contains two separate parts: explaining an Excel formula and evaluating four statements about the Jianying (CapCut) video editing app. Let's address them sequentially.

Excel Formula Explanation

The formula =B5*(A2+A5)*10 performs a three-step calculation in Excel:

First, it adds the values in cells A2 and A5 (e.g., if A2=3 and A5=5, this step results in 8).

Next, it multiplies that sum by the value in cell B5 (e.g., if B5=2, this step gives 8*2=16).

Finally, it multiplies the entire result by 10 (e.g., 16*10=160), producing the final output in the cell where the formula is entered.

Evaluation of Jianying (CapCut) Statements

Statement	Correctness	Explanation
A. "Add picture-in-picture video and set it to fill the canvas"	Incorrect	Picture-in-Picture (PiP) is designed as an overlay; to fill the canvas, the video should be placed on the main track instead.
B. "Use keyframes to set mask animations"	Correct	CapCut allows keyframing mask positions, shapes, or opacity over time, enabling dynamic mask animations.
C. "Chroma key can only抠出 green parts"	Incorrect	CapCut’s chroma key supports multiple colors (green, blue, red, etc.) and custom color selection, not just green.
D. "11 preset blend modes for effects"	Incorrect	CapCut offers more than 11 blend modes (e.g., Normal, Multiply, Screen, Overlay, etc.), typically around 16+ standard modes.

Key Takeaway: Only statement B is accurate. CapCut’s keyframe feature is essential for creating animated masks, while the other claims contain factual errors about PiP functionality, chroma key limitations, or blend mode quantities.

Have you encountered specific challenges with CapCut’s masking or keyframe tools that make these features confusing in practice?
