Rewrite the following radical expressions as equivalent exponential expressions.<br> b. 2(4√3)
IRISSAK [1]

Answer:

2^{3} .3^{\frac{1}{2} }.

Step-by-step explanation:

Here in this problem, we have to rewrite a radical expression as an equivalent exponential expression.

The radical expression is 2(4√3)

Now, 2 ( 4√3)

=( 2 × 4) √3 {Since all the terms are in product form so, we can rearrange it}

= ( 2× 2²) × √3

=2³√3 {Since we know the formula from the property of exponent, xᵃ . xᵇ = x⁽ᵃ⁺ᵇ⁾ }

=2^{3} .3^{\frac{1}{2} }.

Therefore, 2^{3} .3^{\frac{1}{2} } is the required equivalent exponential form. (Answer)
