The rule for multiplying similar bases with exponents:
(a^b)(a^c)=a^(b+c)
In this case we have:
(5^-2)(5^-1)
5^(-2-1)
5^(-3)
The rule for negative exponents:
a^(-b)=1/(a^b)
So in this case:
5^(-3) is equal to
1/(5^3)
1/125
el triangulo que forma el radio es un triangulo equilátero y por lo tanto el lado del hexágono sera de la misma medida que el radio:
lado = radio = 2 cm
como hay 6 lados, lo multiplicamos por 6 :
2x6 = 12 cm
entonces el perímetro del hexágono es 12 cm

Answer:
31
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
using PEDMAS(parentheses, exponents, division, multiply, addition, subtraction) to solve the problem
First, multiply (-5)(2) and 2(-3)
(-5)(2) – 2(-3) + 3
=-10-(-6)+3
=-10+6+3
add -10+6
-4+3
Add -4+3
-4+3
=-1
Therefore, (-5)(2) – 2(-3) + 3 is equal to -1
