Anestetic [448]

Answer:

5/8x+1/2x-4=5

or, 5(2x-4)+8x= 5

or, 10x- 20+8x=5

or, 10x-8x= 20+5

or, 2x= 25

or,x= 25/2

:.x= 25/2

Step-by-step explanation:

first we have to make denominator then we can criss cross multiply. we can make in same point .if there is plus we can subtract and if there is front minus if we take it back it must be plus. then we can put same point then we can divide

Simplify the expression. Assume that all variables are positive. Exponents in simplified form should all be
Rainbow [258]

<u>Given</u>:

The given expression is \frac{7^{\frac{1}{2}} \cdot 7^{\frac{3}{2}}}{7^{-3}}

We need to determine the exponents in simplified form.

<u>Exponents in simplified form:</u>

Let us determine the exponent in simplified form.

Let us apply the exponent rule \frac{x^{a}}{x^{b}}=x^{a-b}

Thus, we have;

7^{\frac{1}{2}+\frac{3}{2}-(-3)}

Adding the fractions, we get;

7^{\frac{4}{2}-(-3)}

Cancelling the common terms, we have;

7^{2-(-3)}

Simplifying the exponent, we get;

7^{2+3}

Adding the exponent, we have;

7^5

Thus, the simplified form of the expression is 7^5
