Question 1 Report

If \(0.0000152 \times 0.042 = A \times 10^8\), where \(1 \le A < 10\), find A and B

Answer Details

0.0000152 x 0.042 = A x 108

1 ≤ ≤  A < 10, it means values of A includes 1 - 9

0.0000152 = 1.52 x 10-5

0.00042 = 4.2 x 10-4

1.52 x 4.2 = 6.384

10-5 x 10-4

= 10-5-4

= 10-9

= 6.38 x 10-9

A = 6.38, B = -9
