2^2/5+ 3^1/10 <br> HELP ASAP

gizmo_the_mogwai [7]

Answer:

$\sqrt[5]{4}$ + $\sqrt[10]{3}$

Step-by-step explanation:

We sure can write 2^2/5+ 3^1/10 as $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$

// use the $a^{\frac{m}{n} } =\sqrt[n]{a^{m} }$ to transform the expression

Convert $2^{\frac{2}{5} }$ to $\sqrt[5]{2^{2} }$ = $\sqrt[5]{4}$ (here a = 2, n = 5, m = 2)

Then convert $3^{\frac{1}{10} }$ to $\sqrt[10]{3^{1} }$ = $\sqrt[10]{3}$ (here a = 3, n = 10, m = 1)

Now we get $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$ = $\sqrt[5]{4}$ + $\sqrt[10]{3}$ . This is the simplified form, which is the answer.

It's many things, it's a binomial, an expression, a linear model.

3x + 5y = 30

GrogVix [38]

Answer:

$y= - \frac{3x}{5} + 6$

Step-by-step explanation:

The given linear equation is

$3x + 5y = 30$

To solve for y, we first subtract 3x from both sides to obtain:

$5y = 30 - 3x$

Divide through by 5

$\frac{5y}{5} = \frac{30}{5} - \frac{3x}{5}$

This simplifies to

$y= 6- \frac{3x}{5}$

$y= - \frac{3x}{5} + 6$
