Question

d) 4^15: 2^26 =
e) 25^8: 125^5 =
f) 16^9:8^12 =
​

Answer 1

Explicație pas cu pas:

d) 4^15 : 2^26=2^30 : 2^26= 2^4=2×2×2×2=16

4^15=(2^2)^15=2^30

e)25^8 : 125^5=5^16 : 5^15 =5^1= 5

25^8=(5^2)^8=5^16

125^5=(5^3)^5=5^15

f) 16^9:8^12= 2^36 : 2^36 =2^0=1

16^9=(2^4)^9=2^36

8^12=(2^3)^12=2^36

Answer 2

$4^{15}\div \:2^{26} =1073741824\div \:2^{26} =1073741824\div \:67108864 =16$

$25^8\div \:125^5 =152587890625\div \:125^5 =152587890625\div \:30517578125 =5$

$16^9\div \:8^{12} =68719476736\div \:8^{12} =68719476736\div \:68719476736 =1$
