a.4×3⁴+5×3⁴
b.(3²)⁵×3⁵
c.(-125)×(-5)⁶
mohon bantuannya
terimakasih
Jawaban:
a. 3⁶
b. 3¹⁵
c. (-5)⁹
Penjelasan dengan langkah-langkah:
a.
[tex]4 \times {3}^{4} + 5 \times {3}^{4} \\ = {3}^{4} \times (4 + 5) \\ = {3}^{4} \times 9 \\ = {3}^{4} \times {3}^{2} \\ = {3}^{4 + 2} \\ = {3}^{6} [/tex]
b.
[tex] {( {3}^{2}) }^{5} \times {3}^{5} \\ = {3}^{(2 \times 5)} \times {3}^{5} \\ {3}^{10} \times {3}^{5} \\ = {3}^{10 + 5} \\ = {3}^{15} [/tex]
c.
[tex]( - 125) \times {( - 5)}^{6} \\ = { (- 5)}^{3} \times {( - 5)}^{6} \\ = {( - 5)}^{3 + 6} \\ = {( - 5)}^{9} [/tex]
Jawaban:
a. 4×3⁴+5×3⁴ = (4 + 5) x 3⁴
= 9 x 3⁴
= 3² x 3⁴
= 3 ²+⁴
= 3⁶
b.(3²)⁵×3⁵ = 3¹⁰ x 3⁵
= 3 ¹⁰+⁵
= 3 ¹⁵
c.(-125)×(-5)⁶ = (-5)³ x (-5)⁶
= (-5) ³+⁶
= (-5)⁹
-5⁹
