Question

5. j) (3⁷×5¹²)²
k) (2¹⁰ •3⁷:(2⁵•3⁶)
VA ROG MULT​

Answer 1

Răspuns:

j) (3⁷ × 5¹²)² = 3¹⁴ × 5²⁴

k) 2¹⁰•3⁷ : (2⁵•3⁶) = 96

Explicație pas cu pas:

j) $(3^{7} *5^{12} )^{2} = 3^{7*2} *5^{12*2} = 3^{14} * 5^{24}$

k) $2^{10} *3^{7} :(2^{5} *3^{6} ) = (2^{10} : 2^{5} ) *(3^{7} : 3^{6} ) = 2^{10-5} *3^{7-6} = 2^{5} *3 = 32*3 = 96$
