Question

va rog ajutor !!!!!!!

A) { 9 la puterea a 2 + [ 5 la a 2 + ( 8 la a 3 : 4 la a 4 + 25 la 1 : 1 la 25) : 3 la a 2 ] : 2 la a 2 } : 2 la a 3
b) [ 2 la 12 x 2 la 18 + 25 la 55 : 5 la 20 - (3 la a 5 ) totul la 10 ] : [ 4 la 2 x 2 la 3 x 2 la 23 + (5 la 2)tot la 25 - (3la 2) tot la 25 ]

Answer 1

$[9^{2} +[ 5^{2} +( 8^{3} : 4^{4} +25:1): 3^{2} ]: 2^{2} ]: 2^{3} =$
$[ (3^{2} )^{2} +[ 5^{2} +( ( 2^{3}) ^{3} : (2^{2}) ^{4} + 5^{2} ): 3^{2} ]: 2^{2} ]: 2^{3} =$
$[ 3^{4} +[ 5^{2} +( 2^{9} : 2^{8} + 5^{2} ): 3^{2} ]: 2^{2} ]: 2^{3} =$
$[ 3^{4} +[ 5^{2} +( 2 + 25 ): 3^{2} ]: 2^{2} ]: 2^{3} =$
$[ 3^{4} +( 5^{2} +27: 3^{2} ): 2^{2} ]: 2^{3} =$
$[ 3^{4} +( 25 +3 ): 2^{2} ]: 2^{3} =$
$[ 3^{4} +28: 4 ]: 2^{3} =$
$[ 81 +7 ]: 2^{3} =$
$88: 8 =11$
b) $[2^{12} * 2^{18} +25 ^{55} :5 ^{20} -(3 ^{5} ) ^{10} ] :[ 4^{2} * 2^{3} *2 ^{23} +( 5^{2} ) ^{25} -( 3^{2} ) ^{25} ]=$
$[2^{12+18} +( 5^{2} ) ^{55} :5 ^{20} -(3 ^{5} ) ^{10} ] :[( 2^{2} )^{2} * 2^{3} *2 ^{23} +5^{2*25} - 3^{2*25} ]=$
$(2^{30} +5^{2*55-20} -3 ^{5*10} ) :(2^{2*2+3+23} +5^{50} - 3^{50})=$
$(2^{30} +5^{90} -3 ^{50} ) :(2^{30} +5^{50} - 3^{50})=$
din experienta cred ca ceva nu e corect in enunt pt ca 5 trebuia sa aiba aceeasi putere in ambele paranteze....
