Answer (3)

8.4 * 10^1 is what I think the answer is

Answered by scc128 | 2024-06-10

to use it in expanded form (4×20)+(4×1)=84

Answered by StanleyTB | 2024-06-10

The product of 4 × 21 is calculated using the distributive property, resulting in 84 . By breaking 21 into 20 + 1 and calculating each part, we see that 4 × 20 = 80 and 4 × 1 = 4 , giving a final sum of 84 .
