Question

scrie sub forma de o singura putere :

a)4,7⁹×4,7¹⁵ b)2,3¹⁸÷2,3¹² c) (3,15⁴)⁶

d)1,5⁴×0,6⁴​

Answer 1

$4.7^9\times \:4.7^{15}=4.7^{24}$

$2.3^{18-12} = 2.3^{6}$

$\left(3.15^4\right)^6 =3.15^{4\cdot \:6} =3.15^{24}$

$1.5^4\times \:0.6^4 => 1.5^4=5.0625 => =0.6^4\times \:5.0625 =0.1296\times \:5.0625 =0.6561$
