$log_4(y+2)=3$
raise each side to base 4
$4^{log_4(y+2)}=4^3$
simplify
$(y+2)}=64$ using the law of logarithms $a^{log_ab}=b$
=>
y=62

Exponents are used when we find the area of a shape, used in banking for finding compounding interest, and used to describe very large and very small numbers. (They are used for many other things, of course, but I don't think you want that kind of list)

You can use exponents to write numbers by writing the exponent for the number of times you are multiplying the base.

Solve each equation. Record your work and check your solution. a. 5(x-2)+(-9)= -7(1-x)

Daniel [21]

The solution for equation is x = -6

Solution:

Given equation is:

$5(x-2) + (-9) = -7(1-x)$

We have to solve the equation

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

Therefore, solve for brackets in given equation

$5(x-2) + (-9) = -7(1-x)\\\\5x - 10 -9 = -7 + 7x$

Solve for terms in left hand side of equation

$5x - 19 = -7+7x$

Move the variables to one side and constants to other side

$7x -5x = -19+7\\\\2x = -12\\\\Divide\ both\ sides\ by\ 2\\\\x = -6$

Thus the solution for equation is x = -6
