Answer:
1. n=0 2. x = 15 and 3. m = -5
Step-by-step explanation:
1. 28^3*32^n = 28^3
Divide both sides by 28^3:-
32^n = 1
n = 0 ( any number to the power 0 = 1)
2. 30^x * 30^5 = 30^20
divide both sides by 30^5
30^x = 30^15
because the 2 bases are the same ( both = 390) we have:-
x = 15
3. a^m * a^3 = 1 / a^2
a^m * a^3 = a^-2
Divide both sides by a*3
a^m = a^-5
so m = -5
Answer:
_17 or -10 i think its -10
Step-by-step explanation:
X²-11x+19=-5
First collect like terms
x²-11x+19+5=0
x²-11x+24=0
Factor
(x-8)(x-3)=0
Isolate values of x
x-8=0, x=8
x-3=0, x=3
Thus
x=8,3
3 √10
I think since a^2+b^2=c^2
Evaluate 7-5{p}+3q7−5p+3q7, minus, 5, p, plus, 3, q when p=1p=1p, equals, 1 and q=7q=7q, equals, 7.

Answer:
Its 23
Step-by-step explanation:
7 – 5p + 3q
= 7 – 5(1) + 3(7)
= 7 – 5 + 21
= 28 – 5
= 23
