To get the product of a whole number itself, always multiply it twice to get the product. Example; 7 x 7 = 49.
Answer:
171.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·10+5·10+5·10+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈171.65064
It would be a great idea to narrowing it down to (2^3)^134 mod 5. now it is easier cause <span> 8 = 3 (mod 5), let's compute 3^402 (mod 5).
</span><span>3^4 = 81 = 1 (mod 5). </span>
<span>Therefore, 3^402 = (3^4)^100 * 2^2 = 1^100 * 4 = 4 (mod 5). </span>
Answer:
q = ±5√5
Step-by-step explanation:
q² - 125 = 0
q² = 125
q = ±√(5 * 25)
q = ±5√5
