Question

Calculati:13la2+5×{2316÷579+[40+2la3×(2la4×5la2÷10-2la2×3la2)]×5}+11

Answer 1

=13^2+5×{2316÷579+[40+2^3×(2^4×5^2÷10-2^2×3^2)]×5}+11
=169+5×{2316÷579+[40+8×(16×25÷10-4×9)]×5}+
11
=169+5×{4+[40+8×(400÷10-36)]×5+11
=169+5×{4+[40+8×(40-36)]×5+11
=169+5×[4+(40+8×4)]×5+11
=169+5×[4+(40+32)]×5+11
=169+5×(4+72)×5+11
=169+5×76×5+11
=169+380×5+11
=168+1900+11
=2068+11
=2079

Answer 2

13² + 5 x { 2 316 : 579 + [ 40 + 2³ x ( 2⁴ x 5² : 10 - 2² x 3² ) ] x 5 } + 11 = 2 000

= 169 + 5 x { 4 + [ 40 + 8 x ( 20² : 10 - 6² ) ] x 5 } + 11 =

= 169 + 5 x { 4 + [ 40 + 8 x ( 40 - 36 ) ] x 5 } + 11 =

= 169 + 5 x [ 4 + ( 40 + 8 x 4 ) x 5 ] + 11 =

= 169 + 5 x ( 4 + 72 x 5 ) + 11 =

= 169 + 5 x ( 4 + 360 ) + 11 =

= 169 + 5 x 364 + 11 =

= 169 + 1 820 + 11 =

= 2 000
