The first option is correct
Answer:
1 / q^30.
Step-by-step explanation:
[(p^2)(q^5)]^-4 * [(p^-4)(q^5)]^-2
Using the law (a^b)^c = a^bc :-
= p^-8 * q^-20 * p^8 * q^-10
= p^(-8+8) * q^(-20-10)
= p^0 * q^-30
= 1 * q^-30.
= 1 / q^30.
Answer:
736
Step-by-step explanation:
(2*(8*8))+(2*(8*19))+(2*(19*8))=A
Answer:
train a weighs 177 and train b weighs 90
Step-by-step explanation:
train a weighs 87 more tons than train b but both combined is 267.
a + b = 267
267 - 87 = 180
divide by two to get the weight of train b
180/2 = 90
add the 87 to find the weight of train a
90 + 87 = 177
check
90 + 90 + 87 = 267
this is my first time answering a question, hope this helped :)
