27^x+2=81

Algebra 2

x = -2/3

Step-by-step explanation:

27 ^(x+2) = 81

Rewrite 27 as a power of 3

27 = 3^3

Rewrite 81 as a power of 3

3^4

3^3^(x+2) = 3^4

We know that a^b^c = a^(b*c)

3^3*(x+2) = 3^4

3^(3x+6) = 3^4

The bases are the same so the exponents are the same

3x+6 = 4

Subtract

6 from each side

3x+6-6 =4-6

3x = -2

Divide by 3

3x/3 =-2/3

x = -2/3

x = -2/3

Step-by-step explanation:

We'll employ our knowledge of indices and exponential resolution to solve the problem.

First, we'll make efforts to resolve this figures such that the bases will be of thesame figure.

Our priority will be on "27" and "81"

27= 3*3*3

27 = 3^3

81 = 3*3*3*3

81 = 3^4

Therefore, let's solve now!

27^(x + 2) = 81

3^3 (x + 2) = 3^4

We'll then use the exponent 3 to expand the bracket that is 3(x+2)

3 ^ (3x + 6) = 3^4

The bases in 3 will cancel out! The equation becomes:

3x + 6 = 4

3x = 4 - 6

3x = -2

x = -2/3

Math is fun

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
