​

Answer 1

Answer:

>> 90×12= 1080......!!!!!!!!!

Answer 2

Answer:

add the exponents algebrically.

example: 103 x 104 = 10(3 + 4) = 107

example: 105 x 102 x 10-3 = 10(5 + 2 + (-3)) = 104

When the operation involves division, subtract the divisor exponent from the numerator exponent.

example: 105/103 = 10(5 - 3) = 102

example: 107/1012 = 10(7 - 12) = 10-5

example: 108/10-3 = 10(8 - (-3)) = 1011

example: (106 x 104)/(103 x 102) = 10(6 + 4 - (3 + 2)) = 105

When the operation involves powers or roots, multiply the exponent by the power number or divide the exponent by the power number, respectively.

example: (105)3 = 10(5 x 3) = 1015

example: (10-7)4 = 10-(7 x 4) = 10-28

example: = (104)1/2 = 10(4 x 1/2) = 102

example: = (1020)1/5 = 10(20 x 1/5) = 104
