a² is the correct answer

the following question answer is a2

(1/a×1/10)^-2 × 1/100= (1/10a)^-2× 1/100= (10a/1)^2 ×1/100= 100a^2/100= a^2 answer

a² is the correct answer of the given question

(a-1*10-1)-2+1/100

Final result :

100a - 1299 ——————————— 100

Step by step solution :

Step1:

1 Simplify ——— 100

Equation at the end of step1:

1 (a - 13) + ——— 100

Step2:

Rewriting the whole as an Equivalent Fraction :

2.1Adding a fraction to a whole

Rewrite the whole as a fraction using100as the denominator :

a - 13 (a - 13) • 100 a - 13 = —————— = —————————————— 1 100

Equivalent fraction :The fraction thus generated looks different but has the same value as the whole

Common denominator :The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractionsAdd the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(a-13) • 100 + 1 100a - 1299 ———————————————— = ——————————— 100 100

Final result :

100a - 1299 ——————————— 100

a^2 is correct answer.
