Choose the correct simplification of the expression 4 times b all over a to the power of negative 10.

a to the 10th power times b all over 4
4a10b
4 over a to the 10th power times b
already simplified

Option B is correct that is

Step-by-step explanation:

Given Expression:

We have to simplify the Given Expression.

We use the following law of exponent,

Consider,

Therefore, Option B is correct that is

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
