Question

(7×10^3)^2 ×(16×10^-4)

Answer 1

Объяснение:

7^2*10^6*16*10^-4=49*16*10^2=78400

Answer 2

Let's solve the expression step-by-step:

(7×10^3)^2 = (7^2) × (10^3)^2 = 49 × 10^(3×2) = 49 × 10^6

Next, we multiply this result by (16×10^-4):

(49 × 10^6) × (16 × 10^-4) = 49 × 16 × 10^(6 - 4) = 784 × 10^2 = 78400

So, (7×10^3)^2 × (16×10^-4) = 78400.
