Answer:
23!+24!+26
Take terms common.
24!=24×23!
⟹23!+24!+26=23!+24×23!+26
⟹23!+24!+26=(1+24)23!+26
⟹23!+24!+26=25×23!+26
You could play around a bit more, but it is not going to be much help. Any calculator can give you the answer as a four-byte floating point value.
23!+24!+26=6.463004×1023
However, grab a calculator that can work with 128-bit integers to obtain the exact value.
23!+24!+26=646300418472124416000026

Answer:
2/√3
Step-by-step explanation:
2tan23°tan35°tan30°tan55°tan67°
= 2tan(90-67)°tan(90-55)° tan30° tan55°tan67°
= 2cot67° × tan67° × cot55° × tan55°
× tan 30°
= 2 ×1/tan67° × tan67° × 1/tan55° × tan55° × tan30°
= 2 × 1 × 1 × 1/√3 = 2/√3
