HOW DO U COMBINE LIKE TERMS in math?? DO NOT LOOK IT UP :) THX
gayaneshka [121]

Answer:

See below

Step-by-step explanation:

"Like terms" are terms with the same variable or exponents.

You can add or subtract these just like you would with regular numbers.

Examples:

2x + 4x = 6x

5xy + 7xy = 12xy

6x^{2} + 5x^{2} = 11x^{2}

Let me know if you need more examples or have any questions :)

(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
