evablogger [386]

Answer: a) 15625, b) 0.2, c) 625, d) 0.008.

Step-by-step explanation:

Since we have given that

a) (5^2)(5^3)

As we know that

a^m\times a^n=a^{m+n}

So, it becomes,

5^2\times 5^3=5^{2+3}=5^6=15625

(b) (5^2)(5^{-3})

So, it becomes,

5^2\times 5^{-3}=5^{2-3}=5^{-1}=\dfrac{1}{5}=0.2

(c) (5^2)^2

As we know that

(a^m)^n=a^{mn}

So, it becomes,

5^{2\times 2}=5^4=625

(d) 5^{-3}

a^{-m}=\dfrac{1}{a^m}\\\\5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}=0.008

Hence, a) 15625, b) 0.2, c) 625, d) 0.008.

What type of expressions are in 3x–2y+7? I asked the wrong question beforehand.
nasty-shy [4]

Answer:

Step-by-step explanation:

3x+2y=7

Simplifying

3x + 2y = 7

Solving

3x + 2y = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3x + 2y + -2y = 7 + -2y

Combine like terms: 2y + -2y = 0

3x + 0 = 7 + -2y

3x = 7 + -2y

Divide each side by '3'.

x = 2.333333333 + -0.6666666667y

Simplifying

x = 2.333333333 + -0.6666666667y
