Question

(5^7+5^6+5^5) : 5^5+9^7:3^10

Answer 1

5⁵(5²+5+1):5⁵+(3²)⁷:3¹⁰=
5⁵(25+6):5⁵+3¹⁴:3¹⁰=
5⁵x31:5⁵+3¹⁴⁻¹⁰=
5⁵⁻⁵x31+3⁴=5°x31+81=1x31+81=31+81=112

Answer 2

Raspuns:
$=5^{2} *(5^2+5+1):5^5+(3^2)^7:3^{10}$
$= 5^{2} *(26+6):5^5+3^{14}:3^{10}$
$=5^5*31:5^5+3^{14-10}$
$=5^{5-5}*31+3^4$
$=5^0*31+81$
$=$$1*31+81$
$=31+81$
$=112$
