Help me please I will mark BRAINLIEST

exponents are rather fuzzy so check my work, just use the same pattern

Step-by-step explanation:

a) 4⁹⁺³ = 4¹² = 16,777,216

b) 6⁵⁺² = 6⁷ = 279,936

c) 8⁶ + 8¹ = 262,144 + 8 = 262,152

d) 7⁸ + 7⁶ = 5,764,801 + 117,649 = 5,882,450

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
