3²x3 ^x= 3^7
Find the value of x

the answer is 3^5 because multiplication is done by adding the carriers

x = 5

Step-by-step explanation:

Rewrite the equation

3^x+2=2187

perform prime factorization of the right side

2187=3^7

3^x+2 = 3^7

equate the exponents of 3 on both sides

x+2 = 7

solve for x

x=5

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
