Question

Efectuati inmultirea:
d)√5 t² · (-6√5 tz⁴)=
Ridicati la putere:
b)(√5a²b)⁴=
d)(√2a³b⁻²)⁻²=
PE CARE il puteti cu acela va rog sa ma ajutati va rog foarte mult :((((

Answer 1

d) rad5·t^2·(-6rad5·tz^4)=
-6·(rad5)^2·t^2·t·z^4=
-6·5·t^3·z^4=
-30·t^3·z^4

b) (rad5·a^2·b)^4=
(rad5)^4·a^2+4·b^4=
5^2·a^6·b^4=
25a^6·b^4

d)(rad2·a^3·b^-2)^-2=
=1/(rad2·a^3·b^-2)^2=
=1/(rad2)^2·a^3+2·b^-2+2=
=1/2·a^5·b^0=
=1/2a^5·1=
1/2a^5
