3:1/6=3*6/1=18/1=18
D

When we divide two fractions, the first fraction remains the same that multiplies the inverse of the second fraction… the multiplication is performed numerator by numerator and denominator by denominator

(2/3)^x-1=27/8, Find x. Please, a step-by-step explanation.

Vaselesa [24]

Answer:

x=-2

Step-by-step explanation:

(2/3)^x-1=27/8

Rewriting the right hand side

(2/3)^x-1=(3/2)^3

We know that a^-b = 1/a^b Hint: { 1/(3/2) = 2/3}

(2/3)^x-1=(2/3) ^-3

The bases are the same, so the exponents are the same

x-1 = -3

x -1+1 = -3+1

x = -2

Solve (2a^x + 1/2b^x)^2

alexira [117]

Answer:

$(4a^{2x} )+2a^{x} b^{x} + \frac{b^{2x} }{4}$

Step-by-step explanation:

The given equation is

$(2a^x + \frac{1}{2}b^{x} } )^2$ ...........(i)

we know the formula i.e.

$(a+b)^{2}= a^{2}+ b^{2} +2(a)(b)$

Applying this formula on equation (i) gives

= $(2a^{x} )^{2} +(\frac{1}{2})^{2}*(b^{x} )^{2} + 2 (2a^{x} )(\frac{1}{2} b^{x})$

Opening the sqaure gives and canceling $\frac{1}{2}$ with 2 gives us

= $4a^{2x} + \frac{1}{4}b^{2x} + 2a^{x}b^{x}$

= $(4a^{2x} )+2a^{x} b^{x} + \frac{b^{2x} }{4}$

which is the answer
