Question

Simplify the expression. (c^-6)(2c^7)

a. 2c
b. 3c
c. 3c^-42
d. 2c^-42

Answer 1

a. 2c

Explanation:

you keep the coefficient (since the first is 1) and add the exponents, so -6+7=1.

so...it becomes 2c^1 or just 2c

Answer 2

Choice a is correct answer.

Explanation:

We have given an expression.

(c⁻⁶)(2c⁷)

We have to simplify above expression.

We use following formula to simplify this expression.

`x^(m)`×
`x^(n)`=
`x^(m+n)`

Using above formula in given expression,we get

2c⁻⁶⁺⁷

2c¹

2c which is required answer.
