4. what value of k solves the equation?
k^-5 = 1/32
k = ?
5. what value of m solves the equation?
2^m = 1/8
m = ?

1) 7⁻³ = 7 * 7 * 7 = 343 but because the exponent is negative
343/1 becomes 1/343. Letter C.
2) 1/3 ⁻⁵ = 1/3 * 1/3 * 1/3 * 1/3 * 1/3 = 1*1*1*1*1 / 3*3*3*3*3 = 1/15 since negative exponent ⇒ 1/15 becomes 1 ÷ 1/15. Remember the rules of division. multiply the 1st fraction to the reciprocal of the 2nd fraction.
1 ÷ 1/15 = 1 * 15/1 = 15 Letter B.
3) 2/4 ⁻³ = 2/4 * 2/4 * 2/4 = 2*2*2 / 4*4*4 = 8/64  negative exponent 1 ÷ 8/64
Rules of dividing fractions:
1 ÷ 8/64 ⇒ 1 * 64/8 = 64/8 ⇒ 8 not included in the choices.
4) k ⁻⁵ = 1/32 * this means that 32 must undergo prime factorization to get the base. k = 2  ⇒ 2⁵ = 32 ; 2⁻⁵ = 1/32
5) 2^m = 1/8 ; m = -3 ⇒ 2³ = 8 ; 2⁻³ = 1/8

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Do you have a picture? ?
