Answer:

Step-by-step explanation:

4x + 23 + 9x - 38 = 180

13x - 15 = 180

13x = 195

x = 15

4(15) + 23= 60 + 23= 83

9(15) - 38 = 135 - 38= 97

21y - 1 + 97 = 180

21y + 96 = 180

21y = 84

y = 4

21(4) - 1 = 84 - 1 = 83

Evgesh-ka [11]

Step-by-step explanation:

Area1=4×3=12cm²

Area2=6×3=18cm²

Area3=(6+3)×(12+4)=9×16=144cm²

Total area = area1 + area2 + area3

Total area= 12+ 18+144=174cm²

Rewrite the expression with a rational exponent as a radical expression.

Nuetrik [128]

Answer:

Rewriting the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression we get $\mathbf{\sqrt[9]{3} }$

Step-by-step explanation:

We need to rewrite the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression.

The expression given is:

$(3^\frac{2}{3})^\frac{1}{6}$

First we will simply the expression using exponent rule $(a^m)^n=a^{mn}$

$(3^\frac{2}{3})^\frac{1}{6}\\=(3^\frac{2}{18})$

As we know 2 and 18 are both divisible by 2, we can write

$=(3^\frac{1}{9})$

Now we know that $a^\frac{1}{9}=\sqrt[9]{a}$

Using this we get

$=\sqrt[9]{3}$

So, rewriting the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression we get $\mathbf{\sqrt[9]{3} }$
