simplify this and give me proper answers with method
​

Answer 1

Step-by-step explanation:

First, use this rule of exponents to rewrite the

b

denominator:

a

=

a

b²×c-¹

Step-by-step explanation:

Given:

a⁴×b⁵×c⁷/c⁸×a⁴×b³

×c-¹

Solution:

=a⁴-⁴×b⁵-³×c⁷-⁸

=a⁰×b²c-¹

=b²×c-¹

Method used:

whenever there is a division symbol with same exponent with different power u should subtract the power with the power of same exponent in numerator
